I bought a PT111 G2 the day before black friday, and have put around 100 rounds through it so far.
Every piece of spent brass Ive collected has a strange "rat-tail" indentation on the primer.
I've inspected the firing pin [without fully disassembling the weapon] and there doesnt seem to be any burrs or chips in it...looks perfectly rounded.
Any ideas as to what could be causing this and whether or not I should be concerned? Also if anyone has had the same experience?

[Included pics are of 115gr FMJ Sig, and Cheapo steel-cased Tula (the only 2 types of ammo I've run through it so far)]

Baffles me too. Seeing it I would swear the firing ping has a knot on it.

Primer wipe is very common in Poly pistols...something to do with the speed of the slide and ejection process. My PT 145 produced brass like that all the time. Welcome to the forum and congrats on that new pistol!

[/QUOTEIt looks like the firing pin is getting hung up after firing. Check the firing pin channel and clean thoroughly.

Primer wipe = the extraction/reload cycle starts before the firing pin has fully retracted. My gen 3 mil pro did this with absolutely no problems.

It's not just your Taurus, I've seen that happen with Glocks and other pistols as well. Typically, it's much ado about nothing.

The only semi auto I own, that doesn't do that, is my PT1911.

I had a PT145 that did that, It would shave off a little bit of primer and it would lodge in the firing pin channel and turn the pistol into a club. I don't know the cure but check that channel out after every time you shoot it or you may be carrying around a club rather that a firearm....

I just looked at some of the brass I save from recent range trips with my 111 G2, and some have it, some don't. Regardless, seems to do fine every time I pull the trigger. :) Glad to know, because I had noticed this issue and never remembered to ask what it was. Primer Wipe. New Gun Knowledge acquired. :D

Sometimes also called primer smear. I never knew either until I acquired my PT 145...the PT1911 just puts a big old crater in each primer..:D

I have no idea if my 4 do it or not (all different brands) because I have never looked. They all go bang every time I pull the trigger so I have had no reason to look. I pick up the brass but don't bother to look.
